- [u32] signature: 'MTSM'
- [u16] version: 3
- [u16] size X
- [u16] size Y
- [u16] size Z
- For each Y:
- [u8] slice probability value
- [Name-ID table] Name ID Mapping Table
- [u16] name-id count
- For each name-id mapping:
- [u16] name length
- [u8[]] name
- ZLib deflated {
- For each node in schematic: (for z, y, x)
- [u16] content
- For each node in schematic:
- [u8] probability of occurance (param1)
- For each node in schematic:
- [u8] param2
- }
-
- Version changes:
- 1 - Initial version
- 2 - Fixed messy never/always place; 0 probability is now never, 0xFF is always
- 3 - Added y-slice probabilities; this allows for variable height structures
